Removing spacing and adjusting Header on Pure and Simple Theme

Hi!

I am pretty new to WordPress and am trying to build a very simple site. I have been prodding around, but can’t seem to work out how to remove the spacing between the main menu and the metaslider on each page. I also want to insert a logo above the header and tagline, but can’t seem to add it above, I can only add the logo as a background image, or have an either/or logo or header. If you have any help, that would be great!

I am using the Pure and Simple free theme and here is the website draft:

Thanks!
